OFFIQ WINDOW-SASH MOUNTING.

Application filed February 7, 1927. Serial No, 166,326.

This invention relates to windows and more particularly to the sash mounting thereof.

The primary object of the invention is to facilitate the cleaning of the outer sides of the Window panes without the necessity of the cleaner climbing out upon the window ledge and thus endangering life and property.

Heretofore attempts have been made to construct window frames which would enable such cleansing operations to be performed in safety but their general adoption has not been accomplished as they have been found unsatisfactory, due to complication of structure, which renders it impossible for those usually engaged as window cleaners to understand the intricate mechanisms employed. 7

Therefore another object of the present invention is to simplify the construction of such devices so as to render the operation thereof readily comprehensible and to make the various parts sufficiently rugged to withstand hard usage and abuse. 'All of the above is accomplished without introducing unsightly, massive and bulky elements, so that such aesthetic sense of the architect or builder as may be. introduced need not be sacrificed to utility.

One feature of the invention is the parting strips which are capable of being retracted into grooves formed in the side rails or stiles of the window frame so as to produce a smooth unbroken surface between the sashes when they are being prepared for cleaning.

Another feature of the invention is the locking bolts by means of which the parting strips are retained in either projected or retracted position.

Still another feature of the invention is its adaptability to use in connection with double-hung sashes, such as are now commonly employed, without necessitating any alteration in the construction and mounting thereof, nor the disconnection of the sash cords therefrom.

A further feature of the invention is the pivoting of the lower portions of the inner stop beads by means of which they may be swung downwardly toward the horizontal to permit the sashes to be withdrawn for cleaning, and the locking means for the stop beads by which they are securely held in normal vertical position.

One embodiment ofthe invention is illustrated in the accompanying drawing wherein v Figure 1 is. an inner view of a fragment of a window and easing therefor showing the same equipped with this improved sash mounting Figure 2 is a vertical sectional View through Figure 1, the broken lines showing the sashesand stop head in position for cleaning the glass;

Figure 3 is an enlarged horizontal sectional View taken on line 33 of Figure 1;

Figure 4 is an enlarged sectional view taken on line 4P4 of Figure 2; p s

Figure 5 is a View taken at right angles to Figure 4, a portion thereof being broken away to more clearly illustrate the details of construction.

Figure 6 is an enlarged fragmentary sectional view taken on line 6-6 of Figure 2 showing the parting strip extended;

Figure 7 is a View similar to Figure 6 showing the parting strip retracted;

Figure 8 is a face view of Figure 7, and

Figure 9 is aview similar to Figure 6 showing a modified form of parting strip locking means.

Referring to the drawings in detail the window frame comprises the sill 10, vertically disposed spaced side railsor stiles 11 and a lintel 12. The side rails or stiles 11 are provided near their upper ends With spaced parallel slots 13 for the reception of the weight pulleys 14. Extending longitudinally of the stiles 11 in a plane midway between the slots 13 are grooves 15 for the reception of the parting strips which will he more fully hereinafter described,

Secured to the opposed faces of the stiles 11 adjacent their outer edges are stop beads 17 which cooperate with the parting strip to form guide ways for the upper window sash 18. A similar stop head 20 is arranged. adjacent the inner edge of each stile and the lower portions 21 of these stop beads are pivoted so that theymay be swung outwardly and downwardly toward the horizontal. A suitable catch 22 such as that illustrated in Figs. 4 and 5 is provided near the upper end of the lower portion of each stop bead and engages a keeper 23 to hold the same in its it t) -ttl normal upright position. It will be readily appreciated that the stop head when in vertical position will cooperate with the parting strip to form guideways for the lower window sash EZ-l.

The parting strip .25 previously referred to comprises a channel member which is movablv titted into its respective groove and provided intermediate its ends with bowed lea l springs 26. it being. understood that any other type of vieldable means may be substituted which will perl'orm the functions of the leaf springs. These springs are secured to the inner faces of the web portions of the channel members forming the parting strip, and bear against the bottom walls of their respective grooves 15 so as to yieldably urge the channel members outwardly into normal position to separate the window sashes.

In order to positively retain the partinp strips in normal projected position the legs of each are provided with aligning slots 27 for the reception of bolts :28 which are transversel slidable in guides secured to the stiles 1.1, it being understood that these bolts and guides are countersunk into the stiles so that their outer exposed faces are tlush with the exposed portions of said stiles. Slot 27 similar to the slots 27 are formed in the legs of the channel members forming the parting strips adjacent the webs and in the same horizontal planes with the slots 27 so that when the parting strips are retracted into the grooves and the bolts projected, they will be tlush with the exposed faces of the stiles so as to permit the outer sash to be readily withdrawn from the frame.

In the modification shown in Fig. 9, the channel members 29 forming the parting strips are provided at spaced intervals with arcuate depressions 30 which are formed centrally with openings 31 for the introduction of thumb screws 32. The heads of these screws are of a size to be wholly within the planes of the exposed faces of their respective channel members so as to avoid contact with the window sashes. 'lhe shanks ot the screws 32 project through the openings formed in plates 23;, tixed to the bottom walls of the grooves 15. Like the parting strips previously descrihtal, the channel members 2. forming the parting strips are urged outwardl by suitable 'ieldable means. such as the s irings 2t; and ohviousl inward adjustment of the screws will move these parting strips into retracted position. while opposite adjustment of the screws will permit the strips to be projected under the influence of the yieldahle means.

lVhile in the foregoing there has been shown and described the preferred embodiment of this invention it is to be understood that minor changes in the details and construction, combination and arrangement of parts. may be resorted to without departing from the spirit and scope of the invention as claimed.

I claim:

A window comprising a frame, side rails in said frame. douhle-hung sashes slidable in said frame, each side rail having a longitudinal groove. therein, a parting strip in each groove and adapted to separate the sashes. and inner stop heads pivoted at their lower ends to the side rails. the parting stri fis being adapted to be retracted into the grooves when the stop beads are moved out wardly on their pivots to permit removal of the sashes without disconnecting the sash cords.

In iOStlIIIUD y that. I claim the foregoing as my invention, I have signed my name hereto.

HUBERT PALLADA.
